Mi hermano me recomendó que dirigiera la pregunta aquí sobre el nivel de tráfico que obtengo contra varios de mis puertos bloqueados.
Ejecuto pfsense 1.2.3, enrutador en puente .
Detrás de pfsense tengo:
1x windows 7 de escritorio
1x Linux ubuntu ejecutando web (aproximadamente 50MB transferidos / día) y servicio ftp (filtrado) y mumble (utilizado por aproximadamente 10 usuarios)
En las últimas semanas he notado un aumento en los hosts que intentan enviar paquetes UDP principalmente a 1 puerto a la vez. De repente, el puerto al que intentan enviar su envío cambia y apenas noto que haya tráfico hacia el puerto anterior.
No he notado un aumento del tráfico en mis puertos web. Snort solo ha bloqueado 2 hosts en un período de 1 semana (pero no está relacionado, ya que no puedo encontrar ese host en mis registros de FW).
Una representación gráfica (splunk) de donde proviene el tráfico: enlace

Ventana de seguridad de 10 segundos del firewall de Pfsense: Myip = mi ip pública

El puerto cambió a 39742 hace 2 días. No recuerdo el puerto antes de eso, pero era diferente. Curioso cuando las solicitudes cambiarán de puerto nuevamente.
¿Debería preocuparme por esto? ¿Esto es normal? Cualquier ayuda muy apreciada
Gracias
